At-Tawbah · 9:4

4. The idolaters who are excluded from the previous ruling are those with whom you entered into a treaty and they honoured the treaty in full. So there will be a complete fulfilment of the treaty with them until the end of the period. Allah loves those who are mindful of Him by obeying His sacred law, which includes fulfilment of treaties, and by avoiding His prohibitions, which include the prohibition of treachery.
